    Oasis, 

    The AIC3204 cannot support this function,  they would need to use the AIC3254 which has a programmable MiniDSP.  The miniDSP would allow them to mix the I2S In with the Decimation filter output (ADC IN), as well as perform other processing.  The AIC3204 is similar to the AIC3254 but it has a fixed function DSP with set processing blocks described in the Applications reference guide.  none of the processing blocks support digitally mixing of I2S input with the ADC input. 

    Best regards,
